- •
DOM is mainly present as acidic and neutral hydrophobic compounds.
- •
Metals are primarily found within the acidic hydrophobic and hydrophilic fractions.
- •
Most metals are associated with high molecular weight DOM (40–100 kDa).
- •
Few metals exist as “free” ions or complexed by low molecular weight DOM.
- •
Reference FA bind many metals while reference HA bind only a few.
